Last-mile fulfilment is the final step in getting an order from a distribution centre to your customer’s front door. It’s the most expensive and complex part of the supply chain, and it has a massive impact on whether a customer will buy from you again. For anyone selling on platforms like Shopee, Lazada, or their own Shopify store, mastering this final leg of the journey is essential for success.

The safety stock formula helps you determine the extra inventory you need to keep on hand to avoid stockouts. A common method is (Maximum Daily Sales × Maximum Lead Time) – (Average Daily Sales × Average Lead Time). This isn’t just theory; it’s a practical calculation that provides a data-backed buffer to protect your sales and maintain customer satisfaction.

If you’ve ever found yourself buried in packing tape and shipping labels as your online store grows, you’ve hit a common ecommerce scaling problem. This is exactly where third-party logistics, or 3PL, comes in.

Running out of stock is a direct blow to your sales and your ranking on competitive marketplaces. A proper safety stock computation is your strategic buffer, the cushion that protects you from a sudden spike in demand or an unexpected delay from your supplier. Think of it as an insurance policy for your revenue stream.

Running an e-commerce brand is tough. You’re the marketer, the product designer, the customer service head—and too often, the warehouse packer. The third party logistics industry exists to take that last, most time-consuming job off your plate for good.

A simple way to calculate a basic safety stock buffer is with this formula: (Maximum Daily Sales × Maximum Lead Time) – (Average Daily Sales × Average Lead Time). This gives you a baseline cushion to protect your ecommerce business from sudden sales spikes and supplier delays, helping you avoid painful stockouts.
